Accepts Healthy Volunteers
Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms
An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.
An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.
Searching Both is inclusive of interventional and observational studies.

This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.
Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.
Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.
Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.
Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.
The sponsor is the organization or person who oversees the clinical study and is responsible for analyzing the study data.

Subjects will take NAC in a dose range of 2.4 g/day to 4.8 g/day which will be titrated to tolerance during an initial 3-month open label period. After the 3-month open label period, patients in each arm will continue taking equal numbers of capsules representing a dosage that has been titrated to tolerance. As an example, the patients tolerating 2.4 g/day, or 4 capsules containing 600 mg of NAC, after 3 months will be randomized to take 4 NAC or 4 placebo (2.4 g/day dextrose) capsules twice daily for the 9 subsequent months. The primary outcome variable will be the response (yes/no) in the SLE Respinder Index or SRI at Month 12 (reduction ≥ 4 points in SELENA-SLEDAI score and therefore also called SRI-4; no new BILAG A organ domain score and no more than 1 new BILAG B organ domain score; and no worsening in Physician's Global Assessment (PGA) score) by ≥ 0.3 points versus baseline). A positive response will also require no treatment failure, defined as the need for non-protocol treatment, i.e., new or increased immunosuppressives or antimalarials; increased or parenteral corticosteroids; or premature discontinuation from study treatment. Corticosteroids can be tapered off at the investigator's discretion, based on disease activity. Four weeks after randomization, once tapered, corticosteroids can only be increased again to the dosage preceding the last taper step; any larger increase will be deemed a treatment failure. In addition, any increase in corticosteroid dosage during the last 3 months of the trial will result in declaration of treatment failure. We will monitor tolerance and safety, and assess SLEDAI, BILAG, FAS, PROMIS, ASRS, prednisone use, liver and bone marrow function as secondary outcomes.
Active Comparator: NAC

Capsules of NAC, each containing 600 mg of NAC between dosages of 2.4 g to 4.8 g daily
Drug: - Placebo
placebo (sugar) twice daily, daily dosage will match that of NAC that was tolerated between daily dosages of 2.4 g and 4.8 g during the open-label titration phase.
